Californians who stream video on ad-supported platforms will no longer have to lunge for the remote when a commercial blares over their show. Governor Gavin Newsom signed SB 576 on October 6, 2025, making California the first state to extend broadcast-style loudness limits to streaming services. The law prohibits ads from playing at a higher volume than the video content they accompany, and it takes effect in July.
How SB 576 closes a gap left by federal broadcast rules
For more than a decade, the federal CALM Act has required cable and broadcast networks to keep commercial audio levels in line with surrounding programming. Streaming platforms, however, were never covered by those FCC regulations. SB 576 directly references the FCC loudness framework and applies the same principle to on-demand video: ads must not be louder than the content viewers selected. The result is a single, consistent volume standard that now spans traditional television and streaming in California.
The practical effect hits millions of households. Ad-supported tiers on services like Netflix, Hulu, Amazon Prime Video, Disney+, and Peacock have grown rapidly, and abrupt volume spikes during ad breaks have become a common viewer complaint. By tying the new state rule to an existing federal measurement framework, lawmakers avoided creating a novel technical standard and instead borrowed one that the television industry already knows how to meet.
What the law requires and who pushed it into existence
SB 576 passed through the Assembly Committee on Privacy and Consumer Protection, which held a hearing on the bill on June 24, 2025. The committee analysis defined the operative prohibition plainly: streaming advertisements may not exceed the audio level of the video content they interrupt. That language mirrors the CALM Act’s core requirement but extends it beyond broadcast and cable to any ad-supported streaming service accessible in California.
The governor’s office described the measure in straightforward consumer terms. In its signing announcement, the administration emphasized that viewers should not be startled or annoyed by sudden jumps in volume when ads appear. By choosing that framing, state officials positioned SB 576 less as an inside-baseball audio rule and more as a quality-of-life protection for everyday streaming audiences. The bill’s relatively smooth path from committee hearing in late June to the governor’s desk in early October reflects how uncontroversial the concept has become since the federal broadcast rules took effect in 2010.
Consumers who want to track the rollout or check whether a particular service is covered can look to state resources. General information about California laws, agencies, and digital services is maintained on the official state portal, which aggregates updates from departments that may eventually handle enforcement or consumer complaints related to streaming ads.
Will platforms lower peak volumes or rely on automated normalization?
One open question is how streaming services will comply. Broadcast networks typically use loudness normalization tools that automatically adjust commercial audio to match program levels after both are produced. Streaming platforms could adopt the same post-production approach, running ads through automated leveling before they reach viewers. But the structure of digital ad delivery is different from linear television. Ads on streaming services are often inserted dynamically, meaning different viewers watching the same show may receive different commercials sourced from different advertisers with different original audio mixes.
That dynamic insertion model creates a technical challenge. Platforms may need to measure each ad’s loudness against each piece of content in real time, or they may require advertisers to deliver assets that already conform to a set loudness ceiling. The latter approach would effectively push compliance upstream, forcing ad production houses to mix at lower average volumes from the start rather than relying on last‑minute fixes.
Some services may choose a hybrid strategy. They could require advertisers to certify that their spots meet specified loudness targets while also running automated checks and adjustments at the point of insertion. This would mirror how spam filters and content-moderation tools supplement contractual obligations in other parts of the digital ecosystem. Smaller streaming platforms, which may not have robust in-house engineering teams, might opt to license third-party loudness control software rather than build their own systems.
What viewers and advertisers should expect next
For viewers, the most noticeable change should be fewer jarring jumps in volume when ad breaks begin. Because SB 576 is tied to established technical standards, the adjustment is likely to be gradual rather than dramatic: as platforms update their pipelines and ad libraries refresh, older, louder spots will phase out. Some users may still notice differences between shows mastered at very quiet levels and those mixed for louder playback, but the wild swings that triggered complaints are expected to diminish.
Advertisers, meanwhile, will have to adapt creative strategies that sometimes relied on sheer loudness to grab attention. With maximum volume constrained, agencies may focus more on distinctive sound design, music, and voice performance to stand out. Clear rules also reduce the risk that a single overly loud campaign will generate backlash or regulatory scrutiny, which could ultimately benefit brands that prioritize viewer experience.
SB 576 effectively brings streaming into parity with long-standing broadcast norms, signaling that as viewing habits shift online, consumer protections are expected to follow. How quickly platforms implement the necessary tools, and how consistently those tools work across a fragmented ad marketplace, will determine whether Californians really stop diving for the remote when commercials come on.
